OIL-LAMP BURNER.

SPECIFICATION forming part of Letters Patent No. 671,464, dated April 9, 190i.

Application led December 15I 1900. Serial No. 40,043. (No model.)

To all whom, it may concern,.-

Beit known that I, FRANK THEODORE WIL- LIAMS, a citizen of the United States, residing at Meriden, Connecticut, have invented certain new and useful Improvements in Oil- Lamp Burners, of which the following is a full, clear, and exact description.

My invention relates to oil-lam ps of the central-draft type, and particularly to the burner construction thereof.

The chief object of my invention is to prevent unsteadiness or flickering of the Iiame. This I accomplish by means which cause the gas and air to be mixed uniformly and in the most effective proportions, so that when lighted a flame is produced of a steady character and of practically uniform height entirely around the burner. Incidentally the construction is such that the wick cannot be Vraised to an unnecessary or dangerous height.

In addition to the foregoing device the construction is such that the user can quickly eX- tinguish the flame.

In the drawing I have illustrated a vertical section and elevation of a lamp-burner of my improved construction.

A is the outer wick-tube. B is the inner wick-tube. C is the wick, movable between said tubes, which wick may be raised or 10W- ered by any well-known wick-lift device. (Not shown.)

D is an extinguisher-hangs resting upon the upper edge of the wick C. This iiange D has a depending wall D2 of a size substantially smaller than the inner wick-tube B, so that air flowing up through the tube B will pass upthrough the space between the wall D2 and said tube B and supply air to the in ner side of the Wick when the same is elevated. To center the part D' within the inner tube B, nibs or bosses D3 may be provided, whereby the air-space between the wall D2 and the tube B may be -of uniform size all around. Obviously the nibs D3 might be formed upon the inner wick-tube B instead of on the part D2. ing-nibs D8 is immaterial.

E is a perforated spreader, the lower edge of which may rest upon a supporting` ledge or shelf D4 in the wall D2, so that when the wick is raised or lifted the flange D, the cy- The shape of the center-- lindrical wall D2, and the spreaderE will move together.

F is a stationary rod which projects upwardly through the top of the spreader and which may carry a stop or cap G, which is preferably adjustable, so that by its position the upward excursion of the wick is limited. In this way by adjusting the parts before using a person cannot elevate the wick to such -a height as to cause the flame to smoke. When the wick is lowered, the iiange D practically covers the space between the wicktubes A and B, and consequently the flame will be extinguished. The' shape, size, or arrangement of the openings D adjacent the inner edge of the flange D and in the Wall D2 is entirely immaterial so long as they are of sufficient number to allow the proper amount of gas to flow out and upwardly to mingle with the products of combustion rising from the outer side of the wick. If desired, the spreader E may have an annular recess E adjacent the perforations or passages D to facilitate the upward Iiow of the products of combustion generated at the inner side of' the wick C.

What I claim isy l. In a device of the character described, in combination, an inner and an outer wick-tube forming between them a wick passage, a flange resting upon and supported by the wick, a Wall depending from the Wick-flange, said wall projecting into the inner tube but of considerably less diameter, thereby affording an annular air-passage to the inner side of the wick, perforations in said Wall adjacent the wick-flange and the inner side of the wick, and a spreader.

2. In a device of the character described, in combination, an inner and an outer wick-tube forming between them a wick passage, a flange resting upon and supportedby the Wick, a Wall depending from the wick-ange, said wall projecting into the inner tube but of considerably less diameter, thereby affording an annular air-passage to the inner side of the Wick, perforations in said wall adjacent the wick-flange and the inner side of the wick, and a spreader carried by said wick-flange.

3. In a device of the character described, in combination, an inner and an outer wick-tube IOO forming between them a Wick passage, a flange restinguponandsnpportedbythe Wick, a Wall depending from the Wick-flange, said Wall projecting into the inner tube but of considerably less diameter, thereby affording an annular air-passage to the inner side of the wick, perforations in said Wall adjacent the Wick-liange and the inner side of the Wick, and a spreader carried by said ange, and means to limit the upward excursion of said Wick-ange and spreader.

4;. In a device of the character described in combination, an inner and an outer Wick-tube forming between them a Wick passage, a flange, a Wall depending from said Wick-ange and projecting into the inner tube but of considerably less diameter thereby affording an annular air opening or passage to the inner side of the Wick, perforations in said Wall adjacent the inner side of the Wick and the inner edge of the Wick-flange, and a spreader.

5. In a device of the character described, in

` combination, an inner and an outer Wick-tube form ing between them a Wick passage, a ange resting upon and supported by the Wick,

a wall depending from said Wick-flange, said- Wall projecting into the inner tube but of considerably less diameter thereby affording an annular air opening or passage to the inner side of the Wick, perforations in said Wall adjacent the Wick and the inner edge of said flange, and means to center said Wall with respect to the said inner tube, and a spreader.

6. In a device of the character described, in

combination, an inner and an outer Wick-tube forming between them a Wick-passage, a ange resting upon and supported by the Wick, a Wall depending from said Wick-flange, said Wall projecting into the inner tube but of considerably less diameter thereby affording an annular air opening or passage to the inner side of the Wick, perforations in said Wall adjacent the Wick and the inner edge of said flange, and means to center said Wall with respect to said inner tube, a spreader, and meanslimiting the position of said Wick-llange and spreader.

7. In a device ofthe character described, in combination, an inner and an outer Wick-tube forming between them a Wick passage, a flange resting upon and supported by the Wick, a Wall depending from said Wick-flange, said Wall projecting into the inner tube but of considerably less diameter than said tube and thereby affording an annular air-passage to the inner side of the wick, perforations in said Wall adjacent the flange and the inner side of the wick, means for centering said parts with respect to the inner tube, and a spreader carried by said Wick-ange and means to limit the upward excursion ot' said Wick-flange and spreader.
